  1. Great human story. It’s a sign that I had to look up Romex not audioquest to find out what it was. Would anyone nowadays really use romex or has it just achieved mythical status as a starting point for comparisons?

  2. I’ve always been taught not to run any signal cable parallel with power cable as it can induce inductance.
    I have heard the 50Hz hum quite audibly from speakers. (I’m in Australia 240V 50Hz and power is 3 wire Active, Neutral and Earth). I am an AV technician by trade and true most of the time that is in commercial setups, not hifi, using balanced audio etc.
    As a rule for myself I always try to seperate power from audio where ever i can, racks in particular and in cable runs. If I need to cross power i do it at a 90degree angle.
    braided or twisted cable also helps.
    Thats just my 2 cents anyway.

    1. Hi Marcus,
      I’m in Sydney & I use rebar chairs to keep my wires, interconnects & cables apart from each other.
      I have also split my +ve & -ve loudspeaker wires two inches apart, using spacers, & doing so has made an audible difference to the sound quality of my home-audio rig.
